xfs: fix xfs_init_attr_trans not handling explicit operation codes
When we were converting the attr code to use an explicit operation code instead of keying off of attr->value being null, we forgot to change the code that initializes the transaction reservation. Split the function into two helpers that handle the !remove and remove cases, then fix both callsites to handle this correctly.
